Filed: 1999-11-10
Abstract: Radiopharmaceuticals comprising molecules that target to N-formyl-methionyl-leucyl-phenylalanine (fMLF) receptor on leukocytes in order to target sites of inflammation for diagnostic imaging are described. The targeting molecules are attached to capping groups that make the entire molecule either antagonists or weak agonists of fMLF receptor and therefore do not elicit a chemotactic response resulting in neutropenia. The preferred targeting molecule is ReO-Gly-lys(Dimethylgly-t-Butylgly-cys-gly) -glu-trp-phe-leu-nle-NHCOcyclopropyl. The invention also relates to the use of combinatorial chemistry to obtain preferred molecules that target sites of inflammation for diagnostic imaging.

Patent CA-2303302-A1 (CA)
Inventor: LEE DAVID D
IPC: G09G3/20
Filed: 1998-08-20
Abstract: To reduce the layout area required by LCD column drivers without suffering a significant decrease in performance, a PMOS-based circuit selects a voltage from an upper set of analog display voltages and a NMOS-based circuit selects a voltage from a lower set of analog display voltages. This reduces the layout area by up to roughly a factor of two compared with conventional column drivers which are CMOS-based. Moreover, in a typical dot inversion scheme, where two adjacent columns select voltages from alternating voltage sets, two adjacent columns can share the same PMOS-based and NMOS-based circuits by using multiplexers controlled by a polarity signal to route the digital display data into the sets of switches. This reduces the layout area by up to roughly an additional factor of two.
